Abstract
The utility model provides a sunken cord full aluminium, include: transposition aluminium silk, polyethylene insulation, the cladding in the transposition aluminium silk outside, polyvinyl chloride anti -corrosion coating, the cladding in the polyethylene insulation outside. The utility model discloses a sunken cord full aluminium is equipped with polyethylene insulation and polyvinyl chloride anti -corrosion coating, can prevent that the wire from being corroded, the damaged by rats to reach damp -proofing effect.
Description
Technical field
The utility model relates to field of cables, refers to a kind of full aluminium underground line especially.
Background technology
At present, the low-voltage supply line that China rural area adopts, has overhead transmission line and two kinds, buried circuit.Buried circuit is compared with overhead transmission line, has many outstanding advantages, such as: buried circuit is without materials such as electric pole, porcelain insulator, cross-arm, bracing wires; Do not bear the pulling force that electric wire deadweight etc. produces, so wire cross-sectional can only be selected by the size of power load, more chance can be had to adopt the wire thinner than overhead transmission line; In underground, be not subject to violent storm, heavy snow such as to freeze at the invasion and attack of natural calamity, do not exist overhead transmission line common fall the accident such as bar, broken string; Because circuit is embedded in underground, not easily destroyed by people at ordinary times, can also stop arbitrarily to link up with behaviors such as starting to exchange fire on overhead transmission line, substantially improve the management work of rural power service; Maintenance workload greatly reduces than overhead transmission line.But underground line also has its shortcoming due to buried underground: because underground line is embedded in underground, easily to be bitten underground line crust by the toy such as muroid, insects; The conductor wire core of domestic common electric wire is generally all formed through bundle strand by 19 strands of solid conductors, because the conductor wire core that twisted by the 19 strands of solid conductor bundles geometry when same sectional area is minimum, and most rounding, but because filament diameter is thicker, the conductor wire core made is comparatively hard, and often pliability can not meet the installation requirement of client; Do not have color to distinguish, be not easy to wiring.
Utility model content
The utility model proposes a kind of full aluminium underground line, solve problem above-mentioned in prior art.
The technical solution of the utility model is achieved in that
A kind of full aluminium underground line, comprising:
Stranded aluminium wire;
Polyethylene layer, is coated on outside described stranded aluminium wire;
Polyvinyl chloride corrosion-resistant coating, is coated on outside described polyethylene layer.
Preferably, described stranded aluminium wire forms by some monofilament aluminium wires are stranded.
Preferably, the quantity of described stranded aluminium wire is seven strands.
Preferably, have one to be positioned at center in described seven strands of stranded aluminium wires, all the other six strands are evenly distributed on around it.
Preferably, the thickness of described polyethylene layer is 0.2mm ~ 0.3mm.
Preferably, the thickness of described polyvinyl chloride corrosion-resistant coating is 0.21mm ~ 0.5mm.
Preferably, described polyvinyl chloride corrosion-resistant coating is red polyvinyl chloride corrosion-resistant coating, yellow polyvinyl chloride corrosion-resistant coating or green polyvinyl chloride corrosion-resistant coating.
The beneficial effects of the utility model are:
Full aluminium underground line described in the utility model, is provided with polyethylene layer and polyvinyl chloride corrosion-resistant coating, can prevent that wire is corroded, damaged by rats, and reaches moistureproof effect; The quantity of stranded aluminium wire is seven strands, have one to be positioned at center in seven strands of stranded aluminium wires, all the other six strands are evenly distributed on around it, thus are arranged with rule, realize core not only rounding but also soft object, avoid due to the irregular stranded and defect of ovalize that causes of core; Polyvinyl chloride corrosion-resistant coating is red, yellow or green, is convenient to wiring and maintenance.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
